Yeah - I think I need a 2.5 making 270 hp. Leaning towards either OMEX/Burton or someone in the US like Beachman or Quicksilver or Focus Power.

With that in mind then use the chance for a serious upgrade in performance. Options:

1) Why stop at just 2.3L...wimp! Bruce Beachman does a nice 2.5L Duratec option.
2) Dunnell used to have a proprietary ECU which is a big downside to my mind - not sure if that is still true but as an alternative maybe look at Raceline http://www.raceline.co.uk/ or Burton Power (p 14-15 of the catalog) for crate engines
3) While I have not, a number of forum members on the east coast have used Quicksilver race Engines http://quicksilverraceengines.com/services.htm
4) Do you have a Caterham? What about dropping the 620R powerplant into your chassis?

I know someone has shoved an EcoBoost into their Seven. But I'm not sure I want to bang my head against it for that long. After 4 years of mistakes I'm ready for a proven solution. Really at this point I'm ok spending a lot more money for something I am confident will work.

Tom Carlin has installed an Ecoboost in a Birkin. If you are looking for 270hp, this crate motor is very cost effective. As delivered, it puts out 258hp. The ECU that comes with it from Ford is programmable to around 310hp. It's also shorter than the 2.5 and doesn't need a dry sump. Neither do you have to buy forged pistons, rods and crank, all necessary to get a reliable 270 out of it.

Or you can step out of the box and find a wrecked '94 - '05 Miata and use the engine and transmission in your car. It takes some fabrication and electrical skills but it can be done. For far less than some of the engines listed above I ended up with a 1,340 lb turbo charged Miata powered Caterham SV which dyno'd at 301 HP at the rear wheels.
